HAWK

Hawks, Ospreys and Kites

Hawks provide many identification challenges. Several species have juvenile and adult plumages and sometimes a dark and light phase.

A good approach in identifying hawks is to start by determining what it is not. Begin by checking its seasonal range and start narrowing down the possibilities form there.

Accipiters

Accipiters are also known as bird hawks. They prey on other birds. They have short wings and long tails for rapid maneuvering through trees.

sharp-shinned hawk Sharp-shinned Hawk
Sharp-shinned Hawks have a slate gray back, dark head, and red barring on the chest. Long barred tail with white, rounded tip.

Young Cooper's Hawk has a brown back, long banded tail and brown streaks on a light chest.

One of the toughest identification challenges involves separating Sharp-shinned and Cooper's Hawks.

The females of both species are significantly larger than the males of the same species.
